"The World to the Dao" is a medical book, belonging to a kind of health book, to the Tao as the number, because the Han people not only do not shy away from sex, but also highly respect, the room is not only related to fertility, but also an important part of the harmony of husband and wife, family harmony, but also the relationship can be healthy and even immortal. It is normal for a woman in the boudoir to read and collect such books, and it is not uncommon to be more direct than this, but as Cai Yan, it is not ordinary to personally make drawings and annotations for such books in the room.

This is comparable to Tang Bohu's spring picture. Of course, the realm of the two sides is superior, Tang Bohu is just superb in skills, and in essence, it is still a kind of male psychology that characterizes women, Cai Yan should not have such an idea, she is more of an academic research.

But Sun Ce was still curious about Cai Yan's academic research. He sat back in front of the bookcase with Ellan in his arms, flipping through the theory and practicing on Ellan. Ellan's face was red, she couldn't answer the question properly, she was a little annoyed, she lay on Sun Ce's shoulder, bit his earlobe, and panted.

"Husband, what do you want?"

Sun Ce pointed to one of the pictures. "I want you like this." Ellan glanced at it and immediately twisted. "This ...... It's humiliating. ”

"No shame, no shame." Sun Ce said, lifted Ellan with both hands, turned around, and let her turn her back to him and sit in his arms. Ellan didn't have many clothes to wear, and they were the clothes in the boudoir, just looming, there was still a vacuum inside, Sun Ce only had to pull her clothes to the waist gap, and then untie her coat, and the two would be skin to skin and intimate. Ellan parted her legs and straddled Sun Ce's legs, feeling Sun Ce's firmness and heat, and before the real battle started, he was already wet.

"You're not good." Sun Ce put his arms around her, his fingers moving over her lower abdomen, and teased.

"Husband...... Husband, don't let me ...... Gaffe. Ellan was confused, raised her hands, hugged Sun Ce's head, turned her head and kissed Sun Ce, her snort was heavy, and the fragrance was lingering. As her name suggests, she has a light fragrance, especially when she is emotional.

"You're not ugly at all." Sun Ce kissed her back. "Especially now that you are the most beautiful."

"Really? I...... I also think it's beautiful. Ellan hugged Sun Ce, her slender waist swayed lightly, and she was a little jerky at first, but she slowly became proficient. Her cherry lips opened slightly, and her breath was like an orchid. Sun Ce was excited, he wanted to drive straight in, but he came to this world for a few years, under the guidance of Yuan Quan, he also had some understanding of the art in the room, knowing that patience is very important at this time, happiness is like wine, the longer it is brewed, the more fragrant it is, if it is difficult to make nine friends without leaking like nine brewing, it is not clear whether he can communicate with the gods, but the comfort of being transparent inside and outside is definitely not comparable to eating fast food.

There is a similar truth in psychology, the more people who can control their desires, the more likely they are to enjoy success. Most of the people who can't control their desires, but are controlled by their desires, can't go far. In the past, when Yuan Quan was there, Yuan Quan mostly controlled the rhythm, and he just had to enjoy it. Yuan Quan is not here today, and Ellan is a novice, of course he must control the rhythm and not ruin his reputation.

Sun Ce cooperated with Ellan while looking at the "Illustrated Explanation of the World's Most Taoist Talks", this article was originally not long, only a few hundred words, at most no more than a thousand, Cai Yan quoted more words than the text, and with pictures, it is also a long volume. At the end of the volume, Cai Yan also wrote an epilogue, which discusses the current surviving books in the room, comparing the advantages and disadvantages, as if it is a collection of books in the room.

Sun Ce compared it with the relevant knowledge in his own memory while reading it, and he was surprised to find that although there was no lack of speculation and fantasy in this article, most of the conclusions coincided with practice. This is also a common problem of empirical academics, not only traditional Chinese medicine. The theory is suspected of being far-fetched, but the conclusion is in line with reality and can withstand scrutiny. And compared with the books in the room that Sun Ce occasionally flipped through before, Cai Yan's book has a lot of creative ideas and corrects many fallacies.

If we forcibly make a comparison, it is probably similar to Wang Chong's "On Balance", although the logic is not rigorous enough, although the arguments cannot get rid of the limitations of this era, we have seen the germ of rationality and the criticism of previous concepts.

It is worthy of those who have read "On Balance", and it is worthy of being the most suitable person to do academic research in this era. If he hadn't read "On Balance", Cai Yan might not have such a line of thinking, and if he hadn't read a lot of books, Cai Yan might not have such a wide range of knowledge. If he is not smart enough, Cai Yan may not be able to synthesize hundreds of academics and become a family.

Of course, if it weren't for his arrival and changing the atmosphere of this era, Cai Yan would not have paid attention to such knowledge and written such works. With the advent of this book, his role is more subtle, but indispensable.

Sun Ce watched it with relish, and there was some little pride, but it was bitter for Ellan. Sun Ce hadn't finished reading it yet, Ellan had already been defeated in successive battles, and she couldn't form an army, leaning on Sun Ce's shoulder and panting, her whole body was weak and weak, and she couldn't even speak intermittently.

"Husband...... Husband, you ...... How are you ...... today? Hold on for so long? ”

"Has it been a long time?" Sun Ce realized that he was abruptly abruptly beautiful, and hurriedly put down the book, picked up Ellan with both hands, and asked her to turn around and face him. Looking at the pair of upright peaks in front of him, Sun Ce couldn't help but bow his head and kiss them. Ellan Wan turned to groan, hugged Sun Ce's neck with both hands, and wrapped her two long legs around Sun Ce's waist. Ellan is not as tall as Yuan Quan, and Sun Ce is like a baby, holding her silky buttocks with one hand, and her back and neck with the other, and sending it slowly.

"Husband, husband, I can't do it, I can't do it anymore." Ellan begged for mercy.

"So what should I do?" Sun Ce was speechless.

"Nine friendships are not leaked, it is a good opportunity to pass through the gods, it is rare once, how can it be wasted." Yuan Quan's voice came from behind, with a bit of banter. Sun Ce looked back, only to find that Yuan Quan was sitting on the edge of the couch at some point, looking at them with a red face and a smile. Ellan exclaimed in surprise and buried her head in Sun Ce's arms, not daring to see anyone. Sun Ce was also a little embarrassed, and his old face was flushed.

"Sister...... Sister, when did you come in? ”

"When you turned her around and used the sage Huaiyu style, I came in, and when I saw that you were working hard, I didn't dare to disturb you."

"Really?" Sun Ce raised his eyebrows, sat beside Yuan Quan with Ellan in his arms, put one hand around Yuan Quan's waist, and his hand slid down her lower abdomen, and the tentacles were muddy. "Sister, it's better to see than to hear, and it's better to see than to do a line, why don't we work together?"

Yuan Quan blushed, pushed Sun Ce away, and pointed at Sun Ce's forehead. "Nine friends, such a good opportunity, you are willing to waste it, I am still reluctant. Lie down, adjust your breath, and I'll help you press it, even if it's a glimpse of the wonderland, it will be very good for your practice. The great war is coming, and if your realm is raised by one point, we will have more hope for the future. ”

Seeing that Yuan Quan said undoubtedly, Sun Ce had to reluctantly withdraw his hand, let go of Ellan, and lay on the couch. Yuan Quan settled Ellan, endured his emotions, and helped Sun Ce massage him one by one. Her technique is skillful, Sun Ce was originally a little reluctant, but after a while, he relaxed and entered a state of sleeping but not sleeping, as if waking up but not waking up.
